RAILWAY TIE PLATE.

Application riled August 26, 1924; Serial No. 734,275.

To all w /10272 it may concern:

Be itknown that I, JULIUs Kutrrirsciinrrr, a citizen of the United States, resit :ing at New Canaan, in the county of Fairfield and State of Connecticut, have invented certain new and useful In'iprovenients in Rail *ay Tie Plates, of which the following is a specification.

This invention relates to a construction for railway tie plates and has for its chie't object a novel combination of structural features contributing to produce an efficient tie plate combining the functions of an ade quate rail support and a rail anchor serving to resist and check longitudinal creeping of the rail.

In carrying out that object the invention has in view to utilize and conserve all of the desirable and practical features of the invention of my application for Letters Patent Serial No. 725053 filed July 9, 192 i, and to combine with such features novel means for obtaining a scientific reinforcee ment of the plate structure throughout, and definitely to provide means whereby the rail may be efiiciently locked to the tie plate, to prevent creeping, by the driving of the spikes through the tie plate and into the tie.

With these and other objects in view which will more readily appear to those familiar with the art as the nature of the invention is understood, the same consists in the novel construction, combination and arrangements of parts hereinafterniore fully described, il lustrated and claimed.

' A practical form of the invention is shown in the accompanying drawing, in which-- Figure 1 is atop plan view of an anticreeper tie plate construction, embodying the improvements contemplated by the pres ent invention.

Figure 2 is an end view tie plate.

Figure 3 is a vertical cross sectional view of the tie plate on the. line 33 of Figure 1, showing a rail in position on the plate and held locked thereto through the action of the track spikes.

Figure 4 is a cross sectional view of the new plate construction, the section being taken on the line 44 of Figure 1.

F'gure 5 is a side edge view of the plate, showing the same from that side provided with the upstanding reinforced clamping hooks.

of the improved The embodiment of the invention shown 111 the accompanying drawings includes in its general organization a plate body designated by the numeral 1., preferably of re'c a shallow depth from the bottom of theplate and are formed blunt with no sharp edges or projections in order that the seating of the plate on the tie will be by compression, instead of by cutting into the fibres of the wood as is COII1H1OI1 Wlil1 many types of tie plates now in use.

At its upper vside the plate body 1 is formed with a fiat or substantially fiat rail supporting seat 5 preferably inclined downwardly and inwardly, and preferably interrupted by the longitudinally extending grooves 6. This top rail seat extends from end toend of the plate body, and is preferably sutiiciently wide to accommodate the bases of more than one rail section, thus enlarging the usefulness of the tie plate, and contiguous to the outer and inner edge portions of the rail seat the plate body is pierced by the outer and inner spike openings or slots 7 and 8 respectively. These are arranged in the usual staggered order thereby to obtain the best spiking results. Also it will be observed, as pointed out. in said application, that the spike slots or openings preferably are arranged in the We tical plane of the bottom r bs 3 and 4 on the plate body, so that the plate is not weakened in any way at the lo ations of the spike slots or openings. 4

In carrying out the plan of reinforcement for the plate body, and to provide for holding it in place, the sameis formed at its ends with the downwardly projecting girder flanges 9. In the present design of the plate body the said depending girder flanges 9, at the ends of the body, are preferably of a crescent or downwardly arched form, and the length of these flanges is of less extent than the width of'the plate. In other words the depending flanges 9 extend across the ends of the plate body between and slightly beyond the tie engaging C0111 pression ribs 3 and 4: with the result of substantially stitlening the end portions of the plate where the reinforcement is most desirable and it will be observed that toward the outer edge of the plate body the girder flanges 9 project beyond the outer edge of the rail seat to give greater stiffness and strength to that part of the plate through which the resu tant of the applied forces usually passes. The flanges 9 project suiticiently below the bottom of the plate body to engage well over the sides of the tie, thus acting in addition to their reinforcing function, as abutn'ients and holding means which irevent. the tie date from movin longitudi-V nally, that is transversely of the tie.

An important and distinguishing feature ot'the present invention is the provision of the rneans for locking the rail against creeping, such means being rendered effective through the action of the spikes. Referring more particularly to that phase of body is provided on the upper side thereof, and contiguous to the outer edgeof the rail seat 5, with a plurality of upstanding clamping hooks 10, which preferably alternate with the outer spike holes orslots 7. These hooks are in the form of lugs or shoulders rising from the top of the plate and formed at their edge portions with vertically disposed reinforcing flanges 11 which give stillness and strength thereto and each of said hooks is provided with an inclined engaging lip 12 which is disposed above and overhangs the outer edge portion of the rail seat The said lip is adapted to be frictionally engaged by the outer flangeof the rail when such flange is forced into the hooks by the pressure of the track spikes when driven through the inner spike holes or slots 8 against the inner flange of the rail.

Preferably the inner spike holes or. slots 8 are arranged diametrically opposite the clamping hooks 10, one of the holes or slots being directly opposite one of the clamping hooks;- And, at what may be termed the outer side of each of the inner spike holes or slots 8, the plate body is provided with an upstanding lug 13 constituting a spike the in \ention it is to be observed that the tie plate abutment, and this lug is stiffened and braced by an integral gusset 1% formed on the plate body between an edge portion thereof andthe outer side'of the upstanding lug 13. The inner bearing face 15 of each lug 13 is preferably inclined to facilitate and, guide the movement of the spike through the hole or slot 8, and serving to crowd the spike with great force against the inner flange of the rail when the inside spikes are driven home into the "tie. The result of this movement of the spikes is to forcibly crowd the outer rail flange into the tapering spaces provided by the overhanging clanipingfhooks 10. Consequently anti.- creepingof the rail will be checked and pre vented by the frictionofvthe spikes against the edgeof the rail base, by the friction of the outer rail flange within the clamping hooks 10, and by the clamping action of the spike heads on the railbaseh FY0111 the foregoing it is thought that the construction, functions and advantages of the hereindeseribed antic-reeper tie plate structure will now be apparent, and it will he understood that minor changes in the form, proportion and details of construction may be resortedto without departing from-the spirit'orsacrificing any of the advantages of the invention;

I claim 1. A construction for tie plates-including a body provided at itsupper side with a rail seat a d at its lower side with a pair of tie compression ribs of'shallow" depth whichare spaced apartto a distance corre spending at least to the width of the rail seat saidbody being further provided at its end edges with depending outwardly arched girder flanges approximately coextensive in length with the width of said rail seat and adapted to engage over the sides of the tie.

A tie plate structure including the plate body provided with alternating spike holes and upstanding clamping hooks contiguous one'edge portion of the rail seat, other spike holes contiguous the other edge portion of the sail seat and disposed opposite the clamping hooks, and upstanding spike abiitinents projecting above the plate body at the outer sides of said other spike holes.

In testimony whereof I hereunto affix my signature.
